In most cases, individuals who have a higher likeability of fruits and vegetables will consume more and reap health-related benefits because of it. However, other factors influence how the body digests, absorbs, and metabolizes the beneficial nutrients found in fruits and vegetables. Biomarkers, like carotenoids are measurable indicators of some biological state or condition. They can be helpful in understanding the relationships between dietary intake of nutrients and the other factors that may influence how a nutrient is being used in the body. Other factors known to influence skin carotenoids include body composition, exposure to environmental pollutants, or illness. Carotenoids give the bright red, orange, and yellow hues to many commonly consumed fruits and vegetables and can be used to track overall fruit and vegetable intake in an individual. Carotenoids are powerful antioxidant agents with properties that lower your risk of cardiovascular diseases, diabetes, and certain types of cancer. They also improve vision and skin protection.
